Episode 19 recap: Li Ran and his grandmother moved into Lei Ming's house.

At that time, Lei Ming intentionally moved a large tree there, while taking care of a small tree himself. Although he had selfish motives initially, he genuinely cared for the children. He even went to take care of the tree diligently even during heavy rain. Later on, even after Lei Ming had left, he would come back to water the tree. In fact, the classmates forgave Lei Ming and hoped that he could return to Class 11. Lei Ming was also very happy about it.

In order to bring Lei Ming back, Sang Xia also made a lot of efforts. Sang Xia approached the school principal and begged him to allow Lei Ming to return. At first, the principal refused, but fortunately, the classmates came and spoke up for Lei Ming, which moved the principal. Eventually, the principal agreed to let Lei Ming return to Class 11, but with a disciplinary action.

Lei Ming continued to perform data analysis for everyone, helping them understand the current situation of the college entrance examination, so that they could set clear goals and understand the efforts they needed to make. He even analyzed their university majors for them. It must be said that Lei Ming put in a lot of effort this time.

After class, Lei Ming told Sang Xia that Cheng Yu Shan and Li Ran would definitely become special admissions students. For them, it was not just a shortcut but also their destiny. Cheng Yu Shan could participate in mathematics competitions, while Li Ran could participate in robotics competitions. They would also qualify for the "Wings Program" interview.

Later, Lei Ming took Sang Xia to Li Ran's address, and they were surprised to find out that Li Ran was living in Shen Yao's basement. Lei Ming later saw Li Ran and his grandmother's small room, which was very small and cramped.

Sang Xia also told Shen Yao's mother that she planned to provide psychological counseling for the top students. In fact, Sang Xia was the person who filmed Shen Yao killing the butterfly in the countryside that day. Sang Xia could clearly sense that there was something wrong with Shen Yao's state of mind, so she wanted to take this opportunity to understand Shen Yao better.

At that moment, Shen Yao was not in the room, so Sang Xia carefully examined everything. Shen Yao's belongings were spotless. In a small corner, Sang Xia discovered antidepressant medication hidden inside a vitamin bottle. She quickly took a photo of it and then placed the bottle back before leaving.

Mr. Wang was still dealing with the impact Lei Ming's departure had on the company. Lei Ming's speech significantly lowered the company's reputation, and Mr. Wang had to handle the aftermath.

Lei Ming brought Li Ran and Li Ran's grandmother to his own house in order to provide them with a better living environment. After all, Li Ran's parents are no longer alive, so the house was vacant. Li Ran's grandmother was very grateful for everything Lei Ming did for them. Lei Ming told Li Ran not to worry about rent and even gave his own room to Li Ran, insisting that Li Ran should not say thank you.

Li Ran was actually quite grateful to Lei Ming. During a history class with Yu Yang and Jiang Qing, the history teacher praised Yu Yang continuously and didn't even pay attention to his stuttering problem. The teacher mentioned that many great people in ancient times also had a stutter, which gradually boosted Yu Yang's confidence.

When Li Ran went to the office, he saw Lei Ming and Chen Jin playing games. Lei Ming asked Chen Jin, a teacher, to coach Li Ran for the robotics competition. Li Ran initially wanted to join the school team, but they didn't want him, so he had to participate individually.

Chen Jin took Li Ran to his own studio, where all the equipment was very advanced. However, Li Ran could only use it after work hours at the company. This time, they were going to build a competitive robot, and they would rely on Li Ran's skills. Cheng Yu Shan also received one-on-one math tutoring. The teacher insisted that Cheng Yu Shan must use the oldest formulas for calculations in order to truly understand mathematics.

The first lesson that Chen Jin assigned to Li Ran was to disassemble a robot. Suddenly, Li Ran remembered that his father had also made a robot using scrap materials from the factory. His father had once told Li Ran that even if it wasn't gold, it could still shine. Soon, the students of Class 11 began their individual studies. Cheng Yu Shan was about to go home when she noticed that the dismantling and construction had already begun. At first, she thought her study area would become messy and chaotic, but when she entered, she found that the room had been redecorated, and her stuffed toys were placed back in their original positions. Cheng Yu Shan knew that her mother had done all of this.

In fact, Cheng Yu Shan's mother also felt sorry for her daughter, and this time she finally stood up for her. At night, Li Ran couldn't sleep, so he messaged Cheng Yu Shan. Both of them were still studying. Li Ran needed help with reconstruction. Cheng Yu Shan readily agreed. In fact, the two of them had similar experiences, and they would pay more attention to each other in class.
